METAL CAR noon.

Application filed December 15, 1924. Serial N'o. 755,825.

This invention relates to metal door constructi'ons for freight cars. y

In the manufacture of metal doors for freight cars, it is extremelyimportant that the 'doors shall be sufficiently strong to resist notonly the outward thrustfrom the `contents of the car, but also thejarringl and f racking strains that such doors are subjected to. It isalso necessary that these doors should be maintained as light aspossible for ease of operation and economy of cost, and should be sosupported that they may be easily operated. It is also desirable thatsuch doors should be so constructed or equipped as to effectivelyexclude the weather. 1

It is an object of this invention to provide a car doorA constructionthat fulfills the above noted requirements, that is both strong, durableand light, that is constructed for effectively excluding the weather,that avoids unprotected joints and thatis supportedjor easy operationand that is simple and inexpensive in manufacture.

With these and other objects in view which will become more apparent inthe'following description and disclosures; this invention comprises thenovel lstructure and combinations hereinafter described and more Vapended claims. n the accompanying drawings which illustrate a preferred'embodiment of this invention and in which similar reference numeralsrefer to similar features in the different views: g

'the T bars 3 and 4 yof the main door. particularly pointed lout anddeined in the *Figure 7 is a f1"agmentary sectional of a modification ofthe front endv structures of the doors. l

Figure 8 is a view similar to Figure 7 of a further modication of thefront end structures of the doors.

Figure 9 is a fragmentary sectional view illustrating a front endconstruction applicable to a single door, with a slightly modifiedpanel.

Referring now to the drawings, it will be noted that this invention hasbeen illustrated in connection with a freight car for It will be notedthat each door consists of Aa frame comprising an upper T bar 3connected by rear edge T bars 5, the heads of which extend at rightangles to the plane ,of the door. The inner iiange of each head isdeformed by being inclined forwardly for wedging relation with theinclined face of a weather strip 6 secured tothe flange of a Z bar 23 onthe adjacent door Vpost 24.

A T bar 7 connects the forward ends of The head of this T-bar lies inthe plane of the door and the flange thereof rprojects outwardly. Theforward iange 7? of this head is slightlyinclined and odset in anoutward direction as shown'in Figures 2 and 7, `or merely inclinedasiindicated at 18 in Figures 8 and 9.

A T- bar 8 connects the forward ends of the T` bars 3 and 4 of thesupplemental door 2. The head of this T bar lies in the plane of thedoor and the flange 8a thereof is directed outwardly and inclinedforwardly to provide a groove or the like having an outer bevelledwall.-The liange 7al of the T bar 7 is adapted to enter this groove and wedgeagainst the outer inclined wall thereof to effectively seal the jointbetween the two doors for excluding the weather.

A corrugated sheet metal panel is riveted or secured to each frame.Eachpanel consists of a plurality, three in the present instance, oflongitudinally extending sections having longitudinally -extending andoutwardly directed corrugations. The panel they are idented as indicatedat'13 to inter-V lock the same,

be 'spot-welded to the corners'of the frame sections 9 of the main doorhave Aheels or flanges 11 at their ends which are formed by bending theterminal metal at right anf gles. These flanges lit against theoutstanding flanges of the front and rear T bars and are riveted theretothus strengthening the door structure and providing a tight joint toexclude the weather. The corrugations of these Apanel sections extendcontiguous to the heels or outstanding flanges of the said bars andsubstantially merge therein to brace or reinforce the same. It will benoted that these panel sections are also se cured or riveted to theflanges of the T bars that lie in the plane of the door, so each end ofeach section is secured by two rows of rivetsv at right angles to eachother. The sides of these panel sections are secured together inoverlapping relation and the upper and lower sections are'also securedto the upper and lower frame members. The marably provided wit a heel 11similar to the heels at the ends and similarly secured.

The panel sections 10 of the supplemental door may have their outermargins provided with heels 11 similar to the 'sections 9. The inner marns thereof are however preferably fiat as s own in Fi ures 1 and 2.

' Instead of riveting or welding the panel sections together, they maybe provided with telescopic folds 11 and 12 as shown in Figure 6. Inreferring to said figures, it will be noted that one panel sectionl hasits fold inwardly offset-to' bring `the outer surfacelof .the sectionssubstantially ush. After these folds are brought into telescopicrelation If desirable, suitable` gusset plates 14 may to increase thestrength and rigidity thereof .as shown in Figure 4.

The supplemental door 2 usually carries a wooden gmb 15"at its forwardend which ma be 7 maybe secured to the head of the T bar 8 and theAjlamb secured in theforward angle o f saidv -har 16.l In the latterconstruct1on,a plate 17 is preferably applied to the Aside`of the jambas shown.

of the panel sections are 'however bent outwardly to lie along theoutstanding flange ofthe T bar 7 to provide heels 11 and they areriveted Vor secured to both adjacent flanges of such T bar. The forwardflange of the front T bary 7 is inclined `forwardly as indicated at 18.The supplemental door 2 lted to the front T bar as shown A v1n gure 2,or an additional T bar 16 (Fig.

has a front angle 19 that slopes forwardly *i and outwardly7 to receivethe inclined end 18 in wedging relationther'eunder and to vthe main door1a shown in Figure 8 excepting that the panel sections have theirattaching ends outwardly offset as indicated at 21 Vtd bring the innersurface of the sections flush withthe back of the T bars. The front Tbar 7 of this-door has its forward flange outwardly inclined atV 18which is adapted v to enter a channel formed in an angular gm of theupper anel section 10is prefermember 22 secured to a Z bar 23 thatembraces the front door-'post 24. The outer clined flange 18 of theT'bar 7. These doors may. be supported in different ways'. One wayconsists of suspending the` same by means of roller hangers 25 whichtravel on -a horizontalA track 26 secured above the doorway. Inthepresent instance, a single roller support is used for each door, Thissupportihg means, however, is not claimed in this; application asv it`is made the subject matter of .a oopending applicatlon:

It will be appreciated that the use of T bars for the door has anumber-of advantages.. First, ithas the advantage that a usedz and thefront'and rear T bars may be readlly fabricated to provide properdeformed angles for weather proofing purposes. In the second place theyimpart rigidity to the door and in the third place they provideoutstanding flanges against which the heels or end flanges of the panelsections may be secured. It will be noted that the end flanges on thepanel sections which are secured to these outstanding flanges n'ot onlygreatly increase the strength of the door, ut at the same time providesa tight weather sealing joint.

We are aware that many Achanges may be made, and ln'umerous details ofconstruction may be-varied through a Wide range without departing fromthe principles of this invention, and we therefore do not purposelimiting the patent granted hereon, otherwise than necessitated by theprior art.
